STEP 6. Check the wiring harness between rear door 
switch (LH) connector D-16 (terminal 1) and ETACS-ECU 
connector C-219 (terminal 7).

NOTE: Also check junction block connector C-204 for loose, 
corroded, or damaged terminals, or terminals pushed back in 
the connector. If junction block connector C-204 is damaged, 
repair or replace the damaged component(s) as described in 
GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between rear door switch (LH) 

connector D-16 (terminal 1) and ETACS-ECU connector 
C-219 (terminal 7) in good condition?
YES : Replace the ETACS-ECU. If the functions described 

in "CIRCUIT OPERATION" work normally, the input 
signal from the rear door switch (LH) should be 
normal.

NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. If the 
functions described in "CIRCUIT OPERATION" work 
normally, the input signal from the rear door switch 
(LH) should be normal.

STEP 7. Check rear door switch (RH) connector D-06 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q: Is rear door switch (RH) connector D-06 in good 

condition?
YES : Go to Step 8.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the functions described in "CIRCUIT 

OPERATION" work normally, the input signal from the 
rear door switch (RH) should be normal.

STEP 8. Check the rear door switch (RH).

Remove the rear door switch (RH). Refer to GROUP 42, Door, 
Door Assembly 

P.42-37

. Then check continuity between the 

switch terminals and the body ground.

Q: Is the rear door switch (RH) in good condition?

YES : Go to Step 9.
NO :  Replace the rear door switch (RH). If the functions 

described in "CIRCUIT OPERATION" work normally, 
the input signal from the rear door switch (RH) should 
be normal.

STEP 9. Measure resistance at the lower metal part of the 
rear door switch (RH) in order to check the ground circuit 
to the rear door switch (RH).
NOTE: Check that the rear door switch (RH) is grounded to the 
vehicle body via its mounting screw.
Remove the cap, and measure the resistance value between 
the lower metal part and ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 10.
NO :  Check the installation of the switch, and repair if 

necessary. If the functions described in "CIRCUIT 
OPERATION" work normally, the input signal from the 
rear door switch (RH) should be normal.

STEP 10. Check ETACS-ECU connector C-217 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.

Q: Is ETACS-ECU connector C-217 in good condition?

YES : Go to Step 11.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the functions described in "CIRCUIT 

OPERATION" work normally, the input signal from the 
rear door switch (RH) should be normal.

STEP 11. Check the wiring harness between rear door 
switch (RH) connector D-06 (terminal 1) and ETACS-ECU 

connector C-217 (terminal 35).
